Hello, I just got an old ATX Power Suuply (20 pin connector) which I want to use to supply my CMRI. The Pwr Supply was removed from a PC and is in perfect...
... It might need a load on the 5 volt circuit. I don't have the values, but some people use a resistor to provide the load. OTOH, Dell and some other big...
... values, but ... accused ... Bruce, Seems that the pinout is pretty standard. Should I have the resistor between any of the +5V and ground? Thanks!...
Yes between 5 and ground. In Bruce's manual in the back is some information. Do remember the resistor gets hot so use a 50 watt of larger ceramic resistor....
See <http://web2.murraystate.edu/andy.batts/ps/POWERSUPPLY.HTM> for possibilities. The article uses wire colors instead of pin numbers. Note the green wire is...
Pierre, This is covered in the user guide in chapter 19, however, you would want to put in an appropriate size resistor over the +5VDC to ground as well as...
Pierre I was fortunate to buy an ATX power supply tester made by Antec at Fry's. I found that all it did was load the 5 volt circuit (red and black wires) and...
Group: A reminder on two points. New ATX power supplies are designed around the newer 3.3 volt logic and my no deliver the 5 volt that you're looking for. Also...

Just a note to give you insights on how the problem has been solved: - My train is divided in two sections; I'm using the CMRI with an USIC node for each...
Yeah, I know you can grind or file them down but is there anything available like flat ones in a round or square shape that cut be put between the rails...
Victor: I haven't seen anything other than surface mounts that might be what you're looking for. They would be a little hard to wire but not impossible. What...
JIm: What do the surface mounts look like and why would they be challenging to wire? Thanks but I'm not looking for a sensor. My idea is a little off the wall...
See http://www.solidstate-lighting.com/pdffiles/SMT/BL-HA133-TRB.PDF for an example spec sheet and note the TINY size and NO leads. Soldering such devices by...
Oh, so I see what you and Jim mean by the difficulty with the surface mounts... :( Like I said Andy, visibilty is not an issue as trains aren't parked on the...
Victor: OK, I see other caught up on the surface mount... not impossible just not fun. I have seen some of the surface mount that have a wide angle of light......
Actually soldering SMT packages to a circuit board is a piece of cake. I can solder LEDs in 603 packages (the smallest available) quicker than I can solder...

The web site is not up right now, I have been updateing it and did something wrong. The signals have been the subject of a clinic at the National convention of...

You might also want to take the switch that used to be on the front that was in series with the power supply and short the two wires. If I am not mistaken, my...
I am using XP Pro adnf VB 6 SP6. Have done all my testing at 9600 baud. My processor runs at 1.8 GHZ. What would be the ideal and max speed setting for...
To add to Jeff's comments Older computers have a UART (Universal Asynchronous Receive Transmit) that had a max limit of 19200. This is true of my Pentium 300...

Jay: I'm 95% sure a Pent 4 at 1.8 will NOT have the slower UART. It's easy to tell. If you change the speed above 19,200 and it doesn't initialize at all,...
Thanks Don...but I don't use a modem. I am on a network and it is attached to a WiMax wireless system. However when I did use a modem before WiMax and...
